Abstract
The invention provides an environment-friendly demanganizing agent used for washed denim, which is characterized by being prepared from water, sulfuric acid, hydrogen peroxide and a complexing agent TLT. The environment-friendly demanganizing agent used for the washed denim comprises the following components in parts by weight: 2.5-4 parts of water, 1 part of sulfuric acid, 2.8-5.5 parts of hydrogen peroxide, and 1-2.5 parts of complexing agent. In preparation, the complexing agent TLT is poured into water and stirred uniformly, the sulfuric acid is slowly poured into the prepared complexing agent TLT solution, and then the hydrogen peroxide is poured in and stirred slowly. The environment-friendly demanganizing agent provided by the invention is easy to use, and quickly neutralizes potassium permanganate in the washed denim. No peculiar smell exists in the neutralization process, no harm exists to the environment, a denim product has good whiteness and good dirty resistance, and the environment-friendly demanganizing agent has high performance/price ratio and is an ideal demanganizing agent.
Description
Technical field
The present invention relates to the wash water field of jeans, especially relate to the method for the potassium permanganate of retaining on the jeans after washing being carried out wash-out.
Background technology
At present; In cowboy's wash water field,, use potassium permanganate and phosphorylated ligand oxygenerating liquid usually in order to make cowboy's various styles and effect; Indigo cowboy is carried out oxidation with the mode of spraying, drenching, be coated with, smear; But, need to remove potassium permanganate in the subsequent disposal because potassium permanganate is bigger to the harm of human body, and remains in the tearing brute force and the ultimate strength loss to a certain degree that can cause fabric on the fabric.The domestic method of removing potassium permanganate at present is to have the material of reductibility to neutralize with Sodium Pyrosulfite, sodium sulfite anhy 96 and oxalic acid etc.But Sodium Pyrosulfite, sodium sulfite anhy 96 with the process of potassium permanganate reaction in, produce a large amount of SO
2, and SO
2Respiratory mucosa there is hormesis, influences workers'health, also environment is caused serious harm; On the other hand, the reaction of oxalic acid and potassium permanganate discharges CO
2, run counter to the low-carbon (LC) mode of life of present promotion, not enough environmental protection, its price is also higher simultaneously, and it is extremely urgent therefore to eliminate above auxiliary agent.
Summary of the invention
The present invention is directed in traditional demanganize agent such as above-mentioned Sodium Pyrosulfite, sodium sulfite anhy 96 and oxalic acid and the existing defective of potassium permanganate, a kind of environmental protection demanganize agent with following characteristics be provided:
(1) removes the potassium permanganate of retaining on the clothing fast, avoid injury, and do not influence the interior quality of clothing human body;
(2) the washed-out sand position whiteness of raising cowboy fabric is eliminated dim sense, makes the washing effect more clear;
(3) meet the regulation of the world, domestic various environmental regulations and regulations;
(4) high performance-price ratio can significantly reduce cost.
The technical scheme that the present invention solves said problem employing is:
A kind of environmental protection demanganize agent that is used to wash cowboy; It is characterized in that: formulated by water, sulfuric acid, ydrogen peroxide 50 and complexing agent TLT; Said each component that is used for washing cowboy's environmental protection demanganize agent is respectively at the shared mass fraction of prescription: 2.5～4 parts in water; 1 part in sulfuric acid, 2.8～5.5 parts in ydrogen peroxide 50, complexing agent TLT1～2.5 part.。
As preferred version, the ratio of each component is of the said environmental protection demanganize agent that is used to wash cowboy: water: sulfuric acid: ydrogen peroxide 50: complexing agent TLT=4: 1: 5: 2.
Said sulfuric acid is that mass percent is 60% sulfuric acid.
Said ydrogen peroxide 50 is that mass percent is 27.5% ydrogen peroxide 50.
A kind of compound method that is used to wash cowboy's environmental protection demanganize agent does; It is characterized in that: prepare burden by following mass fraction: water: sulfuric acid: ydrogen peroxide 50: complexing agent TLT=(2.5～4): 1: (2.8～5.5): (1～2.5); Complexing agent TLT is poured in the water; Stir, again sulfuric acid is slowly poured in the complexing agent TLT solution for preparing, and then poured into ydrogen peroxide 50 and slowly stir.
On the one hand, according to chemical equation: 2KMnO
4+ 5H
2O
2+ 3H
2SO
4=2MnSO
4+ K
2SO
4+ 5O
2↑+8H
2O, the present invention utilize the stability of ydrogen peroxide 50 under acidic conditions, are convenient to storage, and ydrogen peroxide 50 reacts when running into potassium permanganate, and with the potassium permanganate flush away, the atomic oxygen that reaction simultaneously discharges has bleaching action again; On the other hand; Use a kind of multiduty organic complex TLT that has; This complex compound has significant complexing power to impurity metal ions such as the calcium in the neutralizer, magnesium, copper, iron; Mainly contain following effect: (1) can effective blockade metals ion, thereby control the decomposition rate of ydrogen peroxide 50 indirectly, can prevent that jeans from making powerful decline and the broken hole generation because of exploded is too fast.(2) dyestuff is played dissemination, during potassium permanganate on wash-out cowboy dress ornament, prevent the generation of look flower, color spot and other spot shape material.(3) eliminate of the influence of above-mentioned metals ion, improve the whiteness of oxidized position, make oxidized position fabric after reducing more clear, prevented the generation of dim sense coloured light.
The invention has the beneficial effects as follows: easy to use, the potassium permanganate among the neutralization washing cowboy is quick, does not have any peculiar smell, and environment is safe from harm, and cowboy's product whiteness is good, and didirtresistance is good, to cowboy's not influence of inherent physical and chemical index, and very high cost performance is arranged.
